Which process includes the exchange of cultural features between groups?

The correct answer is acculturation, which refers to the process through which different cultural groups exchange and adopt cultural features, ideas, practices, or values. This exchange is typically the result of prolonged contact between cultures, leading to mutual influence and adaptation. Acculturation involves changes in one or both cultures, where aspects like language, religion, food, customs, and social norms can be shared and modified as groups interact with one another.

In contrast, the other processes listed do not involve this reciprocal exchange of cultural traits. Assimilation typically refers to the process by which a minority group becomes integrated into the dominant culture, often losing its original cultural identity in the process. Isolation involves keeping cultural groups separate from one another, limiting any opportunity for cultural exchange. Segregation generally refers to the enforced separation of groups, which can prevent any meaningful intercultural interactions. Thus, acculturation is distinct because it emphasizes interaction and the blending of cultural elements.
